Data Release Seasonal median daily water depths for study wetlands in the St. Croix National Scenic Riverway, the North Temperate Lakes Long-term Research area, and the Upper Mississippi River study area from 2013-2018
Authors: W J Sadinski; F Roth
Date: 2020-05-20 | Outlet: U.S. Geological Survey data release, https://doi.org/10.5066/P9H4VLEM
To relate water levels in our study wetlands to temperature, precipitation, wetland water depth, and amphibian calling activity, we installed one pressure logger in the deepest spot we could find in each wetland. Soon after thawing conditions allowed, we drove a plastic pipe (anchor pipe) into the sediments at the deepest location and secured another pipe to it that contained one pressure logger (Onset Computer Corporation Model U20-001-04 [Bourne, MA, USA]) suspended approximately 2.5 cm above the sediments. We installed additional individual pressure loggers in the upper part of the logger pipes (in air) at select locations to measure barometric pressure for calibrating the submerged loggers’ readings. We measured pressure once per hour and used software supplied by the logger manufacturers to upload and convert data to depth at the end of each season.
Data Release Oregon spotted frog (Rana pretiosa) monitoring data for metademographic analysis 2010-2018, Oregon: U.S. Geological Survey Data Release
Authors: J C Rowe,; Adam Duarte; J T Peterson; C A Pearl; B McCreary; S Galvan; M J Adams
Date: 2020-05-05 | Outlet: ScienceBase
This dataset contains information from surveys conducted 2010-2018 by USGS as part of a long-term Oregon spotted frog monitoring effort in the central Oregon range. Data consist of site, survey, habitat, and species detection covariates, as well as inter-site distance measurements.

Data Release Annotated bibliography of grazing effects on amphibians and their habitats
Authors: J C Rowe; C A Pearl; M J Adams; B McCreary
Date: 2020-03-04 | Outlet: Science Base
Livestock grazing is one of the most common land uses in the western United States, where multiple amphibians of conservation concern use habitats that are grazed. Despite the common intersection of grazing and sensitive amphibian species, there are very few reviews of research related to the issue. USGS researchers compiled and summarized literature pertaining to livestock grazing effects on amphibians and their habitats, with an emphasis on wetland-breeding species in the western United States. Users of the annotated bibliography can utilize an integrated search tool with user-defined criteria to query records and output results. This tool aids users in synthesizing research related to a range of specific questions and should assist land managers in evaluating and implementing grazing while maintaining habitat for wetland amphibians.
Data Release Oregon spotted frog (Rana pretiosa) telemetry and habitat use at Klamath Marsh National Wildlife Refuge in Oregon, USA
Authors: C A Pearl; J C Rowe; B McCreary; M J Adams
Date: 2019-12-13 | Outlet: Science Base
We used radio-telemetry to study late-season movement and habitat use by Oregon spotted frogs (Rana pretiosa) at Klamath Marsh National Wildlife Refuge in Oregon. This data release includes frog location and habitat use data, as well as visualizations of telemetry data. Tracking events occurred roughly weekly between August and December of 2017.
Data Release Nutrients, estrogenicity, and fecal indicators in surface water collected from wetlands in the Klamath Marsh National Wildlife Refuge, Oregon, 2017-2018
Authors: J C Rowe; K L Smalling; C A Pearl; C E Givens; A J Sperry; M J Adams
Date: 2019-12-13 | Outlet: Science Base
The data was gathered to determine the effects of cattle grazing on wetland water quality in the Klamath National Wildlife Refuge in Oregon. Surface water samples from sites representing a range of grazing histories were collected between June and October in 2017 and 2018. Samples were analyzed for nutrients (ammonia, nitrate plus nitrite, nitrite and orthophosphate), total coliforms, E. coli, enterococci and estrogenicity by US Geological Survey laboratories. Basic water quality parameters such as temperature, pH, turbidity and specific conductance were also collected in the field during each site visit. Quality assurance samples (blanks and replicates) as well as method information is also included in the data release.
